I'm on board with this. In order, I think the Iowa offense needs:
1. A dominant OL.
2. An accurate + reasonably-mobile quarterback.
3. Continued recruitment and development of elite TEs.
4. A collection of receivers who can get open and catch the ball reliably, and a collection of RBs who can hang on to the ball.
All these conditions are consistent with KF's offensive philosophy (dominate the LOS, control clock and field position) and Iowa's historical standards (at least under HF and KF). Then sprinkle in some modern features like RPO and you have an effective offense.
For those clamoring for a "spread offense" or some sexy variant thereof, remember what happened to Michigan when they deviated from their core culture and hired Rich Rodriquez to replace Lloyd Carr - a couple decades of mediocrity. Also, too early to tell how the philosophical change will play out in Madison, but I'm not bullish on the Badgers at the moment.
